# 5.1. Customization FAQ

How do I…

…add a new field on a bug?

  Use Custom Fields or, if you just want new form fields on bug entry but don’t need Bugzilla to track the field seperately thereafter, you can use a custom bug entry form.

…change the name of a built-in bug field?

  Edit the relevant value in the template `template/en/default/global/field-descs.none.tmpl`.

…use a word other than ‘bug’ to describe bugs?

  Edit or override the appropriate values in the template `template/en/default/global/variables.none.tmpl`.

…call the system something other than ‘Bugzilla’?

  Edit or override the appropriate value in the template `template/en/default/global/variables.none.tmpl`.

…alter who can change what field when?

  See Altering Who Can Change What.
